wall warts in China? |
|
|
I sell a device that uses a wall-wart transformer for power. The
transformer supplies 12VAC (that's AC, not DC) at 500mA, through a 2.1mm x
5.5mm coaxial plug. Since my company and most of my customers are
USA-based, I supply transformers with a 120V primary.
I have been contacted by a customer in China who would like to buy one, but
he needs it to run on 220VAC, with whatever plug style they use in China.
(I don't know whether we're talking mainland China, Taiwan, or Hong Kong, by
the way.)
He could always just use a 220V-120V stepdown transformer, along with the
120V wall wart. But I'd rather just advise him to shop for an appropriate
wall wart locally. However, I have no idea where one goes in China to buy
things like that.
Are there mail order suppliers, like Mouser or Digikey here in the states,
that efficiently supply China?
Are there local stores that would have something like that? ("Radio Shack
China"?)
Any advice I can pass on to him would be welcome. It would be ironic if
something like this were unavailable in China given that's where they all
seem to come from in the first place!

Hi, Walter:-
Tell me the city and I'll try to give you some useful advice. It's not
Taiwan if its 220VAC.
Not shipping the (useless) wall wart could significantly reduce the
shipping charges as well.
Best regards,

Thanks, Spehro. Let me find out from my distributor and I'll get back to
you.

Old external modems used to use a 9VAC 830mA to 1A transformer wall
wart. The 9VAC was closer to 12VAC when unloaded, and would probably
work, if you could dig up an old external modem from somewhere in China,
where the primary was the right V. The Practical peripherals ones come
to mind.

I did just this, buy locally, for a US 110volt device imported to |
Australia some years ago.
The best thing is for the customer to take the requirements to a
supplier in China, afterall most wallwarts I see in Australia these days
are made in China.
Letting him purchase locally has several advantages, shipping weight of
course, correct wall plug and importantly (maybe not in China) the
device he buys locally will conform to code requirements in that
country. Even if your 110volt wall wart could be supplied from a
transformer it may not conform and if anything ever went wrong Well!!

I want to know where I could refer a customer (a musician, not an engineer)
in order to purchase a wall-wart AC transformer with a 220V primary and a
12VAC 500mA secondary with 2.1mm x 5.5mm coaxial plug.
If the customer were in the USA, for instance, I would tell them that they
could order the equivalent (with 120V primary) from http://www.jameco.com,
or they might find it at Radio Shack, which is a retail chain with many
local stores. In Europe I would refer them to Farnell, I guess.
But I don't know what retail or mail-order stores there are in China.
I have not yet found out where in China this customer lives - the question
is coming to me through my distributor.
Thanks! |

Hi,Walter.
On my opinion,there are a lot of factories in China who sale such
transformer,at least in Shanghai city.
But the price depends on the amount.
You had better find where the customer lives.Of course if you let a
musician buy transformers,that seems difficult.
best regards. |

Call YOUR distributor, get the facts. He is on the spot and should know |
how to proceed.
We have given you a few clues about what to ask.
If you pay I will talk to him.
Send air ticket and I will go and help him!!

I think you guys have a slight misconception of the picture...
I make a little consumer electronic item (a headphone amplifier, used by
electric bass players) - street price $169. My distributor (in the USA) has
a potential customer in China who wants to buy *one* of these. The customer
needs to buy an AC adapter that will work for his local mains voltage.
Again: quantity *one*. I was just wondering whether there are retail
electronic component stores in China, the equivalent of Radio Shack or Fry's
in the USA; or mail order, the equivalent of Jameco, Mouser, etc; or some
other sales channel I don't know about.
There will not be anybody flying to China on the basis of this sale, I think
:-)
In any event, I still haven't been able to find out where in China the
customer lives, so the question is probably moot. |

It was a good try but really I was only joking. |
There are certainly such places in Honkong where I lived for a while
some years ago but in China I don't know.

Walter:
Can you not get a multi-input voltage unit with leads in and out?
I know we can get this sort of thing commercially in the UK, sold by
Friemann & Wolf, but made in Germany. They are universal input
switching PSU's, their distributors in the USA might be able to
assist.

Go to http://www.asiansources.com
This is a web site for magazines listing asian manufacturers for all
these sort of things. The customer can look for a manufacturer in
his/her city, phone them and either buy direct from them, or get a
local agent for their goods.
It is unbelievable how many manufacturers of these products are
in asia.

The customer lives in Suzhou, Jiangsu. 60miles west of Shanghai.
What he'll need is a wall wart adapter with 220V primary, 12VAC 500mA
secondary, and 2.1mm x 5.5mm coaxial plug. Quantity one.
Thanks for any advice you can send my way!
